Comparative Advertising Rules 

Comparative advertising is a widely used marketing strategy where a brand directly or indirectly compares its product or service to a competitor’s. While comparative advertising can drive consumer choice and foster competition, it is heavily regulated worldwide to prevent misleading claims, unfair competition, and reputational harm.

Understanding comparative advertising rules is crucial for advertisers, marketers, agencies, and influencers to ensure legal compliance and maintain consumer trust.
